Miley Cyrus Rocks — But Not For “Ages”

Sorry to disappoint you, but Miley Cyrus won’t be belting out Whitesnake onscreen any time soon.

When Miley celebrated her 17th birthday with a Rock of Ages-inspired party, rumors inevitably cropped up that the Hannah Montana star might be appearing in the big screen adaptation of the hit Broadway musical.

And although it would be totally cool to see the starlet let her hair loose and belt out some Mr. Big, Poison and Journey, the film’s director, Adam Shankman, says it isn’t going to happen.

“It’s way too soon,” Adam, who also directed Miley’s mega-crush Zac Efron in Hairspray, said yesterday when asked about the casting of his upcoming flick.

So where did these rumors start? “She went to see the show and she loved it and then I had to email her and say, ‘I hear you’re starring in my movie. Fantastic Congratulations!” he quipped. “It was just so crazy. She saw the show and that was all.”

Well, that wasn’t all of it. We had our hopes up real high because not only did Miley catch a performance of the show, she reportedly met with the stars backstage…and the cast even performed at her ’80s-themed b-day bash two weeks ago in N.Y.C.

Though we’d love to see her in Rock of Ages, we’ve got to ask — what exactly does she know about that era and how is she going to prepare for the role? She wasn’t even born until 1992!
